5. You’d better use good battery to make the alarm work long, 
some batteries can use more than 1 year.

1. United States NFPA72 tells that the safety of life is to be 
noticed by alarms before fire, to confirm the correct escape way. 
The fire systems help half of residents escape and we should 
help the old people, women and children more because they are 
always the victims.
2. Smoke alarms are not foolproof, they can't prevent or 
extinguish fires, they are not substitute for property or life 
insurance. You need buy some fire fighting facilities.
3. Sometimes the smoke is blocked by objects and can’t reach 
the detector, and if the wind blows the smoke away from the 
detector, the unit won’t work either.

1. Call the Fire Department immediately after confirming the fire.
2. Don’t panic, stay calmly and follow your family escape plan. 
Get out of the house as quickly as possible, don’t stop to get 
dressed or collect anything.
3. Feel doors before opening them to see if they are hot. If a 
door is cool, open it slowly. Don’t open a hot door-use an 
alternate escape route
4. Cover your nose and mouth with a cloth. (preferably wet). 
Take short, shallow breath.
5. Meet at your planned place outside your home, and do a 
head count to ensure everybody go out safely.

I

t is important to test this unit weekly to make sure it is 

working properly. Don’t open the alarms by yourself, return 
them to the seller if improperly, and don’t use fire to test 
your alarms.

1. Press and hold the test button on the cover of the unit until 
the alarm sounds. If it does not alarm, make sure that the unit is 
receiving power and test it again. If it still does no1 alarm, 
replace it immediately or check your battery.
2. The signal flashes once 30 seconds and while it alarms the 
signal will flash once 0.5  second.
3. If the alarm makes low “chirp” sounds every about 30seconds, 
it tells you to exchange your battery.
4. Little smoke will not cause alarms, so misinformation occurs 
only when you blow smoke to the alarms directly or you forget to 
turn on your ventilated facility while your cooking.
5. Sometimes when you smoke the unit will alarm, so you can 
just blow air to it to stop alarming.
